CAR-AXL LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 273,991, dated March13, 1883.

Application tiled February 13, 1883.

tain new and useful Improvements in Itailway- Car-Axle Lubricators; andI do hereby declare that the following is a full, clear, and exact idescription of the invention, which will enable others skilled in theart to whichit appertains to make and use the same,reference being hadto'the accompanying drawings, which form a part ot' this specification,and in which y Figure l is a longitudinal vertical section of my device,showing the car-axle in elevation.`

Fig. 2 is a vertical cross-sectionof the same through line x a; inlFig. 1. Fig. 3 is a perspective view of one of the chairs, with itsspringrollers and pick-up chain removedfrom the axlebox. Fig. 4 is aperspective view of a pair ofthe rollers withthe chain removed. Fig. 5is a longitudinal sectional view through the rollers. Fig. 6 is aperspective view of one ofthe roller-supporting springs orspring-bearings detached from the chair, and Fig. 7 is a detail view ofthe upper end of the spring-bearings, showing the manner of fasteningthem to the roller journalshafts.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of devices for lubricating theaxles of railwaycars in which the oil or other lubricant is fed to theaxle byrollers journaled in spring-bearings, so as to cause them to bearagainst the under side of the axle within the axle-box, in conjunctionwith an endless pick-up chain, which is carried round by theroller-shaft and dips with its free end in an oil cup or reservoirlocated. in the bottom of the ,axle-box 5 and my improvements consist inthe novel construction and arrangement of operative parts, ashereinafter more fully described and.` claimed, wherebyI prevent jumpingof the pick-up or feeding chains in running the cars over rough roads,andwprovide for the satisfactory working ofthe device under allconditions and circumstances.

` In the accompanying two sheets of drawings, A denotes the journal-box,which may be of any approved construction. In practice, I prefer toconstruct my improved lubri- (No model.)

eating device so that it will fit the journalboxes adopted `by theMaster Car-Builders Associatiomlso that it can, be readily fitted intothese boxes; but it is obvious vthat it may "be made tofflt boxes of anyspecial pattern or construction. In the bottom of the box is theoil-reservoir B. y

C denotes the journal; D', the journal brass or bearing, and E is thejournal-'box cover. When adapted for use on `street-cars orelevated-railway cars, my device is of course con. V

structed of such size and shape as `to t the boxes usedon thatparticular class ofl cars.

ln the bottom of the journal-box are placed two chairs (shown atD D) otidentical size, shape, and construction, arranged, side by` side,crosswise in the bottom of the box, but

in reversed positionth atis, with their springseats at opposite sides.Each chair is in the form of a rectangular box ot' a lengthcorresponding to the inside width of thejournalbox and cut away on itsunder side, as shown at a, to form arched ducts for the free passage ofthe oil from 'one end of the box to the other. The chair is cast withthespring-seat E at one end and two vertical lugs or projections, F, inthe opposite corners, which, by bearing against the sides of the box, asshown in Fig. 2 of the drawings, prevent tilting of the chairs by therapid revolutions ofthe axle or jumping ot' the cars. The two chairs areunited on theirsides facing each other by pins b, andare held in placeinside ot' the box besides by the end lugs or projections, F, by meansof a springbail, G, having coils g, the lower end of which is fastenedin ears c in one of the chairs, while its free upper end bears againstthe top ofthe box,just backof the hinged cover E. Thusit will be seenthat no screws orbolts are used to hold the device in placewithinthejournalbox, but that it can be inserted and again `readilyremoved, when desired, without in theleast disturbing or altering theconstruction of the IJO at e e, to hold the yokeI in place. In the freeend of arms H H is lxed .a short shaft or journal, K, on which rollers LL, united by the short tubular shaft M, are journaled. The sides of therollers facing each other are rounded to form an ogee curve or rim, l,and the short shaft M between them is recessed to form ribs or raisedparts m, which engage the links of the endless feed-chain N, the lowerfree end of which dips in the oil in the bottom of the box. By thisconstruction I 'prevent slipping ofthe chain, and by the peculiar curveor rounding of the inner faces of the rollers the chain is preventedfrom being carried over o r jumping the rim ofthe roller by the joltingof the'car, but will-always drop back into its proper position betweenthe rollers, as the links cannot catch on the ogee-cnrved rim l.

The chairs D are ot' such a width that the rollers journaled in the freeends of the springarms H may be depressed down between the sides of thechairs without interfering with'or striking` against the chairs, and bythe arrangement of the wire bearing with its shoulders h h the arms arebrought so low that their free ends can never come in contact with theaxle. Again, by constructing al separate chair for each pair ofoiling-rollers, the rollers of one chair cannot come in conflict withthose of the other; nor can the feed-chains become entangled, as Whereboth sets of rollers with their respective chains are mounted in thesame chair. AvThis construction of the chairs and rollers, with theirappurtenances also, (as has been already stated,) permits of the easyinsertion of the chairs into the journal-box without disturbing any ofits parts. Y To prevent the upper ends of the wire arms H H, where theseare fastened in the rollerjournal K, from being broken bythe knockingagainst them of the rollers or sudden jerks of the cars, I insert thatpart of each arm through a tube or sleeve, 7a, by which the wire isreenforced and its strength and durability greatly increased. This alsoprevents contact between the rollers and arms between which they arehung, which is apt, by the rapid revolutions of the rollers, to cut thewire arms, and thus render them useless.

Another important advantage which results from my improved arrangementof the oilingrollers in separate chairs is, that the axle-jourvoir.

nal is oiled in four different places, instead of only two, thusthrowing up a much thicker lm of oil against thejournal, over which itis distributed evenly by the bearing-brass which' It is obvious thatthis device may be applied to shafting and the journals of machinerygenerally as well as to the journals of Iocomotives and railway-cars. l

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States y 1. The combination, withthejournal Gand journal-box A, of the two chairs D D, placed, side byside, crosswise in the bottom of the box, and connected on the sidesfacing or impinging upon each other, each chair having structedwith thespring-seats E, having notchesl e, corner lugs or projections F, andarched oilducts a, substantially as and-for the purpose shown and setforth. v

4:. The yielding roller-bearings constructed with the parallel arms H H,spring-coils I, and yoke J, in one piece,.and having shoulders h h wherearms H leave the spring-coils, substantially as and for the purposeshown and set forth.

The combination of the chairs D, having seats E, notched atc, andyielding roller-bear- IOO ings consisting of the parallel arms H,spring- Y ycoils I, shouldered at h, and yoke J, all in one piece, andadapted to tit the notched seat of the chair, substantially as and forthe purpose shown and set forth.

7. The oiling-rollers L, having an ogee annular curveor bevel, t, on thesides facingthe feed-chain N, substantially as and for the purpose shownand set forth.

S. The combination of the journal-box A, chairs D, provided with thespring-supported rollers L M L, having feed-chains N, and bailfasteningG, bent to form the spring coils or loops g, and bearing with' its upperfree end against the roof of the journal-box, substantially as and forthe purpose shown and set forth. y i

In testimony that I claim t'ne foregoing as my own/I have hereuntoaffixed my signature in presence of two witnesses.
